HAIR-CLIPPER SWEAT-GUARD.

SPECIFICATION forming part of Letters Patent N0. 432,076, dated. July15, 1890.

Application filed November 13, 1889. $erial No. 330,356. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH KILBURN PRIEST, a citizen of the UnitedStates, residing at Nashua, in the county of Hillsborough and State ofNew Hampshire, have invented a new and useful Sweat-Guard forHair-Clipping Machines, of which the following is a specification.

My invention relates to improvements in hair-cuttin g machines of theclass well known to the art.

It is a well-known fact that if a polished metallic surface is pressedagainst the sweaty surface of a persons skin the metal will cling and bemoved along said surface with dif ficulty; and it is the object of myimprovement to furnish an attachable and detachable sweat-guard whichmay be placed upon the lower side of a hair-cutting machine and preventall contact between said plate and the skin of a person whose hair isbeing cut. I attain this object by the devices illustrated in theaccompanying drawings, in which- Figure l is a perspective view of theunder side of a hair-cutting machine with one form of sweat-guardattached. Fig. 2 is a side view of sweat-guard a. Fig. 3 is a plan ofamodification of a. Fig. 4 is a side View of Fig. 3. Figs. 5, 6, 7, and8 show different forms which the sweat-guard may assume and still.retain its essential feature. Fig. 9 is comb-plate.

Similarletters refer tosimilar parts throughout the several views.

A, Fig. 1, represents a hair-cutting machine, showing the lower surfaceof its comb-plate. The machine I will not describe, as it is of theclass of machines shown in my patent of November 27, 1888, No. 393,450,the main features of which are well known.

a represents one form of sweat-guard, attached to the under side of themachine by lugs b b, which enter the notches (Z (Z in its com b-plate.This form of guard is preferably made of thin brass, having perforationse e. The guard rests upon the comb-plate at its straight sides; but itscentral portion h is bulged up from the comb-plate in such a way as toraise the parts h from the plate, forming a raised bearing or ridge onwhich the machine may rest and thereby preventing the smooth surface ofthe comb-plate from com ing in contact with the flesh.

The sweat-guard shown by Figs. 3 and 4 is a strip of brass, with ribs 71i struck up from an unperforated surface of brass.

Figs. 5, 6, 7, and 8 show different forms of views of sweat-guards madefrom wires.

The essential feature in this invention is the fact that this deviceintervenes between the polished surface of the comb-plate, presentingthe smallest possible contact with the surface on which the machinerests, and is attachable to and detachable from the machine.

I do not broadly claim a corrugated sweatguard, for such an one is shownin patent to Noble, No. 290,839 nor do I claim, broadly, attachabledevices for the comb-plate of clipping-machines, as there is a varietyof such attachments already patented.

I would remark that, while the principal use for my sweat-guard is inconnection with barbers clippers, there is a growing demand for it inconnection with power sheep-shearing machines. It is found in practicethat when the sheep and the atmosphere are warm a man can shear a sheepin a short time, but if cold it will take many times as long to do thesame work. The reason for this is that when it is warm the tallow whichis so abundant in the wool becomes fluid and presents no obstruction tothe free passage of the cutters, but the moment the temperature is belowa certain point this tallow becomes a sticky substance, which clings tothe cutters. This applies especially to the lowercomb-plate, whichpresents its entire lower surface to the body of the sheep and is to thegreatest extent subject to this obstruction. It is evident that thelarger the surface of cutter exposed the greater the obstruction; also,it is evident that my sweat-guard placed upon the comb-plate of asheep-shearing machine will present a much smaller surface to saidcontact, and of course will meet with much less resistance, therebylargely overcoming the great obstacle which stands in the way ofsuccessful sheepshearing by power. Iwould also remark that the guard isnot only useless in' a warm day in connection with a sheep-shearingmachine, but the cutter is better Without it, making its removaldesirable.

What I claim is- In a shearing or clipping machine, the combination,with the comb-plate, of a sweat-guard consisting of a plate havingribbed projec' tions which lie below the smooth surface of thecomb-plate, said plate having ears which project from its ends to claspthecomb-plate IO in such a way as to be attachable to or detachable fromthe same, essentially as described.
